- This inventionrelates to a window frame having a screen guiding rlb on the mner edge of,"and integral with, an" upright 'OLIJESICEE member thereof, anda screen frame slidable on the rib.

7 The object of the invention isto provide a improvedtform of the rib whereby a thick and massive form is imparted thereto, re- .ducing. iability of breakage of theintegral rib from the casing member.

Of theaccompanying drawings forming a part of this specificatiom- Figure 1 is a fragmentary perspective view, showing a portion of a window frame, the outside casing member ofwhich is provided with my improved guiding riba Figure 2 is afragmentary horizontal sec tion, showing a portion of theoutside casing memberhaving the improved guiding-rib, a 7

portion of the pulley stile, a portion of an upper sash, and a portion of a screen frame provided with a spring, .the screen frame and spring being engaged with the rib.

Figure 6 is ure5. A Figure 7 is afragmentary sectional view, showingportions of two outside upright casing members, and portions of two upright screen-frame members. Figure 8 is a view'similar to Figure 7,

a section on line 6 6 of Figshowing a modification.

Figure 9 shows separately a portion of one of the outside casing members.

The same reference charactersindicate the member, 13the outside vertical casing mem ber, and 14 the pulley stile, the upperportion of which supports the pulleys on which are Figure 3 is a section on line 33 of Fig-- trained the sash cords supportingthe usual "sash weights movable in'th-e vertical, well formed by the members 12 and 13 and the'stile 14. The stile isjoined to and connectsthe members 12'and 13, as usual. 15jdesignates a portion of the stool or sill member-of the casing, joined asusual to the lowerends-of the casing members and stile. ;The,in11er f edge portion of the outside member 13 has a;

sash guiding face 35, and projects across the .3

sash-guiding inner face of thestile to cooper-r ate with the stile and the usual parting bead parting bead and the inside stop head, as usuaL; p y

The inner edge 16 in guiding the upper sash 17. The lower sash (not shown) is guided by the stile, the 7 of the outside member-5'13} is provided with a longitudinal rib,.which is an integral part of the member, 'andhasa] 'lip-guiding'inner face 20, a screen-guiding outer. face 21, and an; intermediate spring' guiding face-22, on which a spring] attached The face 21 to a Screenframe iss'lidable.

is in a plane parallel with the outer sideiof;

the casing member l3, and is considerably. wider thanthe face 20, and provides awidem insecteexcl'uding bearing for a portio'nof the screen frame. [24 designates onejof theup right members of ascrfeen frame iniwhich 1s The two side faces intersect the bottom face 27, to form a groove which is deeper at one I edge than attheothenthe width fofthe side" face 26 being such that the SCIBGIl fIELIIISV is] adapted to be moved ontwardly from the po- L' sition'shown by Figures 2 and 4, across the" rib face 22. V

28' designates a curved end portions of which bear on the bottom of the screen groove and are secured thereto by fasteners 29, the spring'being' provided with orifices 30, receiving said fasteners and prefi metal spring, the

erably elongated, as shown by Figure 5, ito 'f permit .the straightening displacementiofi the spring, as hereinafter described. Theicurva ture of the spring is such that its midlength portion normally projects outside the narrow 7 face 26 of the groove, and is in slidable contact with the spring guiding rib face 22. On the inner edge of the midlength portion of the spring is an outwardly projecting confining lip 31, held by the spring in slidable engagement with the inner rib face 20, as

shown by Figure 2, to prevent removal of the screen frame from the window frame. 7 The narrow inner face of the rib" is parallel with the outer face, 21, is offset from the-sash guiding face and is arranged to guide the spring lip 31. i p

The rib: includes a reinforcing fillet portion 33 integral with the rib and the casing member'l3and having abeveled fac'e 33 extending between the lip guiding face 20 and the sash guiding face 35. a i

T hearrangement of said faces is such that the'portion of the integral rib formed in part by the fillet" portion 33 is wider "than the spring guiding face 28, the fillet portion imparting aniassive form to the inner portion 1110f the rib, whereby liability of breakage of the rib from the casing member 13 is reduced and the fillet portion compensating for the 7 reduction of the cross section of the rib caused by the formation of the wide outer face 21 ithereon. This is a marked advantage it being evident that the member 13 would be rendered us'elessand require replacement if a considerable portion of the rib were broken 0E; r

Another advantage of the described form of the rib is, that the beveled face 33 cooperates with the narrow wall of the screen groove in forming a recess 32 in which the lip 31 is exposed, to permit its displacement by a finger or a suitable tool, into' the screen groove, as shown by Figure 4. When the lip is thus displaced the screen maybe moved outwardly, in the direction indicated by the arrow in Figure 4, and thus removed from the window casing. r 1

Each of the two upright members 24 of the screen frame may be provided with the described groove and spring, as shown by Figeither spring permitting the removal of the screen from the casing.

The spring-guiding face 22, and the portion of the spring bearing thereon, may be transversely' fiat, as shown by Figure 2, or

curved, asshown by Figure 4. Only one of the upright members 24 of the screen frame may be provided with the described groove and spring, the other member 24 being pro- ..Fi-gure 4-,

, vided with a shallow groove 35, contacting with the rib face 22, as shown by Figure 8.

The-movability of the sash 17 is such that it may be moved to expose the opening 32 and permit access: to the lip 31, as indicated by I claim:

A window casing including a vertical outplemental face of a screen frame, a narrow inne'rface 20 parallel with the-outer face, offset from the sash guiding face 35 and arranged to guide a lip'on a screen frame spring, a spring-guiding face 22between the inner and outer faces, and a reinforcing fillet portion 33 integral with the casing member vand rib and having a beveled face 33 extending' between the lip'guiding face 20 and the sash gulding face 35, the arrangement of said faces being such that the portion of the integral rib formed in part by the fillet portion is wider than the spring guiding face 28, the fillet portionimparting a massive form to the inner portion of the rib, whereby liability of breakage of the rib from the casing member is reduced, the fillet portion compensating for the reduction of the cross sec tion of the rib caused bythe formation of the wider outer face 21 thereon.

In testimony whereof I have affixed my signature. i
